The event “will include music, comedy and a ‘rally,’” according to the permit, which was released this afternoon. Messrs. Stewart and Colbert had told their viewers that they would be hosting competing protests, one to “restore sanity,” the other “to keep fear alive,” but later said they would combine them around the Capitol Reflecting Pool.

Lanyards for the event will describe it as the “Rally to Restore Sanity And/Or Fear” and, after Mr. Stewart welcomes the crowd, Mr. Colbert will enter.
